Abstract We herein describe an asymmetric α-allylic allenylation of β-ketocarbonyls and aldehydes with 1,3-enynes. A synergistic chiral primary amine/Pd catalyst was identified to facilitate the utilization of 1,3-enynes as atom-economic and achira

The use of alkylthio electrophiles in synthesis has remained elusive because of the lack of a suitable reagent that is practical and of excellent enantioselectivity and appropriate reactivity. In this work we introduce a novel alkylthio reagent based

Highly enantioselective α-arylation of simple ketones has been achieved by chiral primary amine catalyzed asymmetric retro-Claisen cleavage of β-diketones. This mild organocatalytic strategy enables the construction of α-aryl tertiary carbon stere

We report an arene-containing chiral primary amine as a dual aminocatalyst and ligand: the π-coordinating aminocatalyst/palladium synergistic catalysis for asymmetric allylic alkylation of α-branched β-ketocarbonyls. The use of arene-containing ch

We herein report a synergetic chiral primary amine and rhodium catalysis for asymmetric coupling of β-ketocarbonyls and alkynes. A series of β-ketocarbonyls could be applied to afford linear allylation products, bearing all-carbon quaternary center

An enantioselective primary amine-catalyzed total N-selective nitroso aldol reaction (N-NA) was achieved through the oxidation of primary aromatic amines to the corresponding nitrosoarenes catalyzed by selenium reagents and 30% H2O2. This protocol pr

Asymmetric fluorination of α-branched aldehydes catalyzed by chiral primary amines under mild conditions has been developed. Both enantiomers could be obtained with good yields (up to 96%) and a high enantioselectivity (up to 90% ee) by a simple swa
